Sin(x) begins at (0,0) and oscillates in a range between (-1, 1). Cos(x) begins at (1,0) and oscillates in a range between (-1, 1). Tan(x) has vertical asymptotes and has a range of (-inf, inf). Csc(x) is 1/sin(x), and it restricted from the region (-1, 1)....
How do you integrate cos(x)? To integrate cos(x) we find the antiderivative of cos(x) using the Fundamental Theorem of Calculus and derivative rules. Since the antiderivative of cos(x) is sin(x), the integral of cos(x) is equal to sin(x) + C.A...
asin(A) = bsin(B) = csin(C) When there is an angle opposite a side, this equation comes to the rescue. Note: angle A is opposite side a, B is opposite b, and C is opposite c. 3. Law of Cosines (the Cosine Rule): c2 = a2 + b2 − 2ab cos(C) This is the hardest ...

To enter trigonometric functions on your calculator, locate the corresponding buttons labeled with the function names (e.g., sin, cos, tan). Input the angle value and press the appropriate function button to obtain the desired ratio or angle. 7.3 What is the difference...
HUH? The solution you show in ans does not follow from what you have written above that. So it is literally impossible to know what you are doing since you have not provided useful information for us to answer.
